After you’ve uploaded a data file, if you’re not able to modify the feature type in Decanter AI, try the following troubleshooting steps:

Scenario 1: In excel, when there are decimal data, excel may convert them to scientific format (eg. 1.2345 -> 1234.5 E-3). Due to the characters in scientific format data, Decanter AI will automatically assign those columns as categorical. To resolve this, check your data in notepad for data that contains “E+” or “E-” characters to determine if this is what’s causing the issue.

Scenario 2: When there are null data in the dataset, some system impute those fields with N/A or NAN. If a numerical column contains these character data, Decanter AI will automatically assign the column as categorical. To resolve this, check your data in notepad for data that contains "N/A", "NaN", "NA", "NAN" characters to determine if this is what’s causing the issue.

Scenario 3: If the column doesn’t contain any data, only has the feature/column name, Decanter will assume the column is a categorical column. If this column is needed, fill in the correct data in the fields, or perform imputation before uploading to Decanter AI.

If after trying the above steps you're still not able to modify feature types in Decanter AI, please create a ticket here and we'll be happy to help.
